SPRING FASTENING DI EVIOE.

Application filed Ji11y 13, 1914. I Serial No. 850,544.

' To all whom it may concern:

Be it known that 1, JOHN Sermon, Jr., a citizen of the United States, and a resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Spring Fastening Devices, of which the following is a specification accompanied by drawings.

This invention relates to spring fastening devices for electrical conductors of the type shown in my United States Patent Reissue No. 12,642, granted to me April 23, 1907, and the present invention, while not dilferent in principle from said devices, has for its ob ject to provide a construction of terminal clip more especially suitable in those instances in which a resistant member may be preferred which is integrally connected at both ends to one member of theclip for strengthening purposes, instead of being connected at one end only with the other end left free.

There are certain peculiarities of construction which must be observed in forming a spring terminal clip in the manner about to be described, which will be set forth in this specification as illustrated in the accompanying drawings of two preferred forms of clip, in which-'- Figure 1 is a perspective view of one form, and Fig. 2 is a similar view of another form.

Referring to the drawings, the clip is preferably formed of a piece. of flat metallic ribbon having greater width than thickness,

.bent into U-shaped form. one leg forms a V-shaped body member and the other leg forms a V-shaped spring member situated opposite and normally separated from the body member, but adapted to enter the body member.

In Fig. l A represents the body member which is' adapted to be secured to a base or support and B represents the spring memher. The resistant member shown at Gin Fig. 1, is adapted to lie between the body and spring members, and is bent intermediate ts length to form an angular V-shaped wire engaging portion, the apex of wh1ch projects toward the spring member in the illustration of the device shown, and 18 adapted to enter a slot in the spring member and coact with said spring member to clamp a conductor in defined position therein.

I have found that under some circumstances, itmay be desirable to have the re-,

sistantmember (J integrally connected at each end with the body of the metal from which it is cut, and in order that the strip or ribbon forming the resistant member C may be bent at an angle, as shown projecting toward the opposite member, it is necessary that the member A be'likewise bent at an angle at the point E, for instance, otherwise the strip 0 could not be bent inwardly without stretching of the metal.. I therefore form the bend D in one member and, slot said member centrally at E at 'the'bend to forma recess, leaving the strip U integrally attached to the body of the member at each. end. The strip C is thenbentas-indicated to form a resistant member, with the apex projecting in a direction opposite to the apex of the member out of which it is formed. The opposite member, which may be the spring member C is also preferably bent intermediate its length at F and. is preferably slotted at the bend at G as shown, so that the slot or aperture G may be pressed over the resistant member C, as indicated in the drawings, and the apex of the spring member projects into the recess formedin the opposite member.

121 the form of the invention shown in Fi 2, the body member H is bent at J intermediate its length, and slotted centrally at K, the strip of metal L forming the resistant member, being bent as indicated oppositely to the bend .l to cooperate with the spring member 0. Both forms of. the invention are variations of the same device, but obviously other modifications could be readily devised, having the resistant member formed of a strip of metal cut out of one of thefmcmbers of the device and left with its ends formed integrally with the body of the metal.

I claim and desire to obtain by Letters Patent the following:

1. A fastening device for electrical conductors comprising a body member and a spring member, each of said members being bent intermediate their length in a similar manner to form V-shaped portions, one of which is adapted to enter the other, when the members are pressed together, one of said members being slotted centrally in a longitudinal direction extending on each side of the apex of the bend, and the strip of metal 7 thus removed being bent into V-shape in the opposite direction to the bend 'in the slotted metal at each end, to form a resistant memberadapted to pass through a-slot in theop- .posite member and coact with said opposite member to clamp a conductor. I v

2. Afasteningdev ce for electrical conductors, comprising two-oppositely disposed and normally separated members, each of said members being V-shaped, and one of said members ,being provided at its apex with a recess formed by cutting out a ribbon,

' which said ribbon is also V-sha'ped,its apex projecting in a-direction opposite to the apex 'flof said member, both ends of said ribbon ijectin'g V-shaped being secured to said member,'the V-shaped apex of one of said members being adapted to project into the recess thus formed on the opposite member, and to engage the proribbon upon said oppositev n member, the V-shaped apex on one member andthe. V-shaped ribbon upon the other Wire beposed and normally separated members each of said members being V-shaped, and one of said members having aribbon stamped out of the metal, which said ribbon is secured at both ends to the vmember out of which it is formed, said ribbon extending in a direction opposite to the adjoining portion of the member of which said ribbon is formed, the projecting ribbon upon one of said members being adapted to enter a slot formed by ciitting away the main body portion of the other of said members, the ribbon on one of said members and the main body portion oi the other of said members being adapted to grasp a Wire between them.

In testimony whereof I have signed this presence of two subscilfib specification in the ing witnesses.
